Thanks for the replies.
It sounds like it will probably just end up being a non-event as far as signal analysis goes, so the prudent thing to do may be to simply wait and see what happens when the poop finally hits the fan before looking into any new test equipment.
Not the usual approach I like to take in these looming deadline situations, but given the wave of information vs. misinformation surrounding this event and now the added delay in implementing the DTV changeover, I am still generally very much in the dark as to what to expect with any of this anyway.
